In this particular story, if there's any truth to it then it's basically extortion. They could have just said that due to their usage profile they will need to switch to an enterprise license for the next billing period . Instead they tried to extort it within 24h lol.

And of course you have to buy a whole year of service (lol). This last thing is a symptom of a degenerate market with few competitors. No company that fears competition would try to pull that stunt.
